Paton ER0BS RBILG DH0SM WJOHN RKELL RPARK JFQ TSMIT EWILD CPAT0 I called Mr. Francis Coon at the Wisconsin Alumni Research Foundation. Mr. Coon is examining tissues from shore birds for trace quantities of pesticide resi dues. Previous results had given unidentified peaks in gas chromatographic analysis. Following the work reported by Jensen and Widmark at U. of Stockholm and by Holmes, Simmons, Tatton (Nature 216 Pg. 227, 1967) he is reexamining tissues up to 4 years old to see if the unknown peaks are chlorinated biphenyls or chlori nated terphenyls. The customer in this case is Director of Wildlife Research, Dept, of Interior. Walter W. Dykstra is one of the top men. Mr. Coon indicated that the Division of Wildlife Labora tories, Dept, of Interior, had been working with Aroclor 1242, 1248, 1254 and 5442. He requested 50-100 g. quantities of the same materials which I agreed to send. He was told these were not pure compounds but contained numerous isomers of chlorinated biphenyl and terphenyl. These will be used as standards in gas chromatograms using electron capture detection to compare with un knowns from tissues. Mr. Coon said he was also working for other customers on this same subject but he declined to name who they were. He also said we should expect a publication on this same subject eminatlng from California. He had read this unpublished report. Mr. Coon will discuss results with us from time to time provided they do not conflict with the interests of his clients. ' ms IN. 10 REV. 11-65 W. R. Richard DSW 200660 STLCOPCB4052438
